Vedclass · Answer

(B) The given reaction is $H_2X_2 + 	ext{heat} ightleftharpoons 2HX$.$1$. The reaction is endothermic because heat is absorbed in the forward direction.$2$. According to Le Chatelier's principle,an increase in temperature favors the endothermic reaction.$3$. The number of moles of gaseous products ($2$ moles of $HX$) is greater than the number of moles of gaseous reactants ($1$ mole of $H_2X_2$).$4$. According to Le Chatelier's principle,a decrease in pressure favors the direction with more moles of gas.$5$. Therefore,high temperature and low pressure favor the formation of $HX$.

In the gaseous equilibrium $H_2X_2 + \text{heat} \rightleftharpoons 2HX$,the formation of $HX$ will be favoured by

In which of the following reactions will an increase in pressure shift the equilibrium in the backward direction?

Assertion : $A$ catalyst does not alter the equilibrium constant of a reaction.
Reason : The catalyst forms a complex with the reactants and provides an alternate path with lower energy of activation for the reaction; the forward and the backward reactions are affected to the same extent.
